1.方法是修改系统的下的默认名称。放在博客上就当我记住了哈哈！

#include <windef.h>

LRESULT CALLBACK CBTHookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
	HWND hwnd = (HWND)wParam;
	if (nCode == HCBT_ACTIVATE)
	{
		SetDlgItemText(hwnd, IDOK, "终于把你改了");
		SetDlgItemText(hwnd, IDCANCEL, "哈哈，开心");
	}
	return 0;
}

int MyMessageBox(HWND hwnd, TCHAR *szText, TCHAR *szCaption, UINT uType)
{
	int ret;
	HHOOK hHook = SetWindowsHookEx(
		WH_CBT,
		CBTHookProc,
		NULL,
		GetCurrentThreadId()
		);
	ret = MessageBox(hwnd, szText, szCaption, uType);
	UnhookWindowsHookEx(hHook);
	return ret;
}

main函数中调用
MyMessageBox(NULL, "缺少系统组件，请重新安装", "提示", MB_OKCANCEL)；
